Eaton’s surge capacitor offering provides a cost-effective solution to absorb energy generated during surges events – lightning strikes, switching surges, equipment failures, etc. Electrical surges are common occurrences on power systems, which can be damaging to sensitive equipment such as transformers, generators, motors, reactors, and other similar type equipment with insulated windings.

Construction features extended-foil elements, mechanically crimped with a laser-cut aluminum foil active edge. Solderless connections eliminate localized heating and cold solder joint failure modes, assuring exceptional uniform current distribution resulting in outstanding transient performance. Laser cut process precisely controls a uniform rounded edge reducing the electric field stress, significantly increasing the discharge inception voltage (DIV) to the highest design margin in the industry.

Eaton’s capacitor design has been field proven in a variety of applications. Product expertise is leveraged to make a standard design capable of being tailored for custom needs such as indoor and outdoor applications, pole-mounted, open air, metal enclosed and mobile bank solutions and specialized needs including shunt, series, High Voltage Direct Current (HVDC), Static Var Compensation (SVC), filter applications and micro banks.

Eaton's capacitor units are designed, constructed and tested to provide unparalleled performance in the harshest environments. The tank is constructed from titanium stabilized 409 stainless steel, robotically welded and painted with epoxy primer and urethane topcoat. This construction features a copper impregnation fill tube, nickel plated terminals and patented bonding techniques. Extra creepage bushings are available for contaminated and high altitude needs. Units are validated to ANSI C57.12.29 coastal environment standard.
